Hey guys,
Recently I was advised in perchasing this W200 /RGB200mW by the comunity during a thread i started asking questions about a project i wanted to build.
Since then the Item has arived in super fast shipping, and I thought id make a little review and a tuturial also on how to controll it with a simple Arduino Microcontroller that you can pick up realy cheap.
Here I will be posting 2 controll methods, code and schematics.
________________________________________________
W200 /RGB200mW
SPECS (as reported by Shenzhen Optlaser Technology Co., LTD )
This little thing is heavy! It has a fun inside to keep it cool and as of far i havnt notices the unit heat up.
As you see the unit has to adjustment screws on the front the align the two mirrors inside on 1 axis,
the seccond axis is controlled by the screws on the side.
When mine arived it was only every sooo slightly out of alighment that with 5 meteres it is not noricable but after that you do see a little bit of colour seporation in the beam, with hint of red to one side and a hint of blue to the eother side with green in the middle.
I think this was due to the shipiing process as the mirrors would have goten nocked around a little whipe in transit.
I still have not gotten around to aligning it properly as im tooo scared i will only make it worse haha.
The PCB on the top, dose not show any signs of short cutts, "bodge wires" or slopy soldering.
It has 3 ports on the side that are for the PWM controll for each laser. The pins are labeld clearly wish silkscreen on the pcb.
There is another plug socket for 12V DC and a mistirois 3rd plug on the right wich i have no idea what it dose.
If some one knows it would be awsome!! I applyed 12v dc to that plugtop and a red laser shun, and i was to scared to burn it out and imediatly disconecetd it.
mystery plug with no silkscreen labling.
Over all great laser for its price, and the beam is as close to white as youll get for this price rang (almost perfectly white, althowe beam always looks blue on my iphone -_- )
Heres the tuurial part.

For Ideviual colour controll
This uses 1 pot to scroll threw the brightness and a single button to change wich diode you have selected.
How to wire it.
Ofcorse instead of wiring it to the LED, you wire it to you wire each one to the +'s of each colour.
the -'s all conect to gether to nurtual.
________________________________________________
The seccond method
This method will have the diode slowly fade between all the colours, and even mixing other colours in to such as purple pink, aqua, ad so on.
For this method, You simple conect Red to pin 11, Green to pin 10, Blue to pin 9, Cathodes to GND.
Heres a video of this method. (mind you colours do not come out right due to iphone)

Code:
/*
Fade RGB LED Smoothly through 4 colours
Fades an RGB LED using PWM smoothly through 4 different colours pausing for 1.5 seconds on each colour.
Connect an common Cathode RGB LED with appropriate resistors on each anode to your Arduino Uno;
Red to pin 11, Green to pin 10, Blue to pin 9, Cathode to GND.

your soft gave me some good ideas, lets see how can I make mine work..
